Where do Manchester United start with this game? Defensively, they were ragged and didn't learn their lessons from conceding twice at set-pieces against Arsenal; that was evidenced when Milenkovic, unmarked, easily headed in the opener. They were sluggish at the start of the second half, losing the ball on countless occasions. Whilst Onana didn't cover himself in glory for Gibbs-White's goal, neither did any of United's defenders as they allowed Forest the time and space to create; and were duly punished. It's a wakeup call ahead of next weekend's Manchester derby and one they'll need to heed if they want to grab a win against their old Mancunian rivals.
